The molecule can undergo a pseudorotational rearrangement called the Bartell mechanism, which is like the Berry mechanism but for a heptacoordinated system. [5] Below 4.5 °C, IF 7 forms a …

Here, we study the structure and stability of IF7 and its binding properties to GS, by using several biophysical techniques (fluorescence, circular dichroism, Fourier transform infrared and …

2020年4月15日 · The activity of Synechocystis sp. PCC 6803 GS is regulated, among other mechanisms, by protein-protein interactions with a 65-residue-long, intrinsically disordered …

2017年9月1日 · Glutamine synthetase (GS) catalyzes the ATP-dependent formation of glutamine from glutamate and ammonia. The activity of Synechocystis sp. PCC 6803 GS type I is …

Apical/equatorial exchange in IF7, first analysed by Bartell, shows fluxional behavior of mixed character, similar to that observed for IF5. We conclude by animating the fluxional behavior of …

IF7 is a natively unfolded, 65-residue-long protein, homologous to the carboxy-terminal region of IF17. Both proteins have abundance of positively charged amino acid residues and a high …

We describe a regulation mechanism of the cyanobacterial GS activity that is different from the classical adenylylation mechanism present in many prokaryotes. The Synechocystis system …

七氟化碘是一种无机物，化学式为IF7，为无色有霉烂臭味的气体，冷冻后成无色晶体。 化学性质很活泼，可与除 铂系元素 以外的所有金属和大多数非金属反应。 七氟化碘可用过量的氟和碘 …

1999年6月22日 · Our data suggest that control of GS activity is exerted by regulating the levels of IF7 and IF17. Glutamine synthetase (GS; EC 6.3.1.2) is the pivotal enzyme of nitrogen …

2003年8月1日 · Here, we study the structure and stability of IF7 and its binding properties to GS, by using several biophysical techniques (fluorescence, circular dichroism, Fourier transform …
